'Master' in the Bible

They say, "We speak persuasively; we know how to flatter and boast. Who is our master?"

Then the king will be attracted by your beauty. After all, he is your master! Submit to him!

I will give you thanks before the nations, O Master! I will sing praises to you before foreigners!

Look, as the eyes of servants look to the hand of their master, as the eyes of a female servant look to the hand of her mistress, so my eyes will look to the Lord, our God, until he shows us favor.
